  distortion + lambda*rate

24
For a fixed lambda, rate would represent the filesize, while distortion is
25
the quality. Is this equivalent to finding the best quality for a given max
24
rate is the filesize
25
distortion is the quality
26
lambda is a fixed value choosen as a tradeoff between quality and filesize
27
Is this equivalent to finding the best quality for a given max
26 28
filesize? The answer is yes. For each filesize limit there is some lambda
27 29
factor for which minimizing above will get you the best quality (using your
28 30
chosen quality measurement) at the desired (or lower) filesize.
